3 Claims.

This invention relates to a screen and has particular relation to a screen for windows, doors and similar wall openings.

An object of the invention is to provide, in a screen, a novel type of screen frame specially adapted not only for clamping the margins of the wire mesh screening but also for drawing the screening taut in the frame.

Another object of the invention is to provide, in a screen, a novel type of frame whereby the margins of the wire mesh screening may be readily clamped by the frame in construction and released when it is desired to renew the screening material.

It is a further object of the invention to provide a screen having a transverse tension bar which will not only strengthen the frame but which will assist in drawing the wire mesh screening taut in the construction of the screen.

A further object of the invention resides in the provision of a sheet metal screen frame which will not only clamp the margins of the wire mesh screening but which may be readily adjusted in dimensions to snugly fit the opening to be screened.

With the above and other objects in view the invention has particular relation to certain novel features of construction, arrangement of parts and use, an example of which is given in this specification and illustrated in the accompanying drawings, wherein:

Figure 1 is an inside view of the complete screen, shown partly in section.

Figure 2 is an edge view.

Figure 3 is a sectional view taken on the line 33 of Figure 1.

Figure 4 is a fragmentary, sectional view illustrating the frame in position for assembly with the screening.

Figure 5 is a cross-section view taken on the line 5--5 of Figure 1.

Figure 6 is a fragmentary, cross-sectional view taken on the line 6-6 of Figure 1.

Figure '7 is a fragmentary, cross-sectional view taken on the line 'l-! of Figure 1.

Referring now more particularly to the drawings wherein like numerals of reference designate the same parts in each of the figures, the numerals I, I designate the side members of the screen frame, the numeral 2 designates the upper end member and the numeral 3 designates the lower end member. The side members and the upper end member are of substantially similar construction. They are formed of sheet metal and are approximately rectangular in cross-section but the side members and upper end member have the marginal outwardly extending flanges 4, 4 and 5 to fit against the outer side of the window or door casing. The lower end member 3 does not have this marginal flange.

The frame members are formed. by bending, the sheet metal thereof into approximately a rectangular shape with the flanges 4 and 5 formed at the outer margins. by creasing the metal outwardly, as clearly shown in Figure 4. One of the free margins is folded inwardly and terminates in a longitudinal free flange 6 extending the full length of the frame member and which diverges inwardly from the folded portion thus providing a V--groove l. The frame member 3 is formed similarly excepting it is not creased? outwardly to form the flange 4. The other free margin of the frame member is opposite the groove 1 and adapted to seat in said groove, as shown in Figures 3 and 5, when the outer and inner sides of the corresponding frame members are forced together, that is into parallel relation, as also shown in Figures 3 and 5.

The numeral 8 designates the wire mesh screen- The above described frame members may beassembled into a rectangular frame with their free margins inside of the-frame and the margin of the screening 8 inserted between the free margins of the frame members. The outer and inner sides of the frame members may then be forced" into parallel relation, as shown in Figures 3 and 5, and the margins of the screening 8 will thus be clamped in the corresponding grooves'l, as clearly shown in Figures 3 and 5. The frame members may be permanently secured in said: clamping-melation by means of clamp bolts, as 9, which are fitted inwardly through the outer sides of the frame members and screwed into the nuts III which are fitted outwardly through the inner sides of the frame members. These clamp bolts and nuts have the heads II and I2, respectively, which clamp against the corresponding sides of the frame members to hold said frame members securely in clamping relation with the screening 8.

The frame members may be secured together, at the corners, in any preferred manner. As shown they are secured together, at each corner, by the outer and inner angular brackets l3 and I6, the outer bracket having the marginal inwardly turned flanges l5 and I6 which fit against the outer and inner margins of the corresponding frame members, as more clearly shown in Figures 3 and 5. The inner bracket [4 is complementary to the outer bracket l3 and is inwardly turned at its margins forming the inner flange H and the outer flange 18 which embrace the corresponding frame members.

The clamp bolts 9 and nuts ID, at the corners of the framework, pass also through these corner brackets above described, as shown in Figures 1, 2 and 5.

The frame may be adjusted so as to snugly fit into the corresponding wall opening. To provide for this adjustment the ends of the frame members which fit into said corner brackets areprovided with longitudinal slots l9, l9 through which the corresponding clamp bolts 9 extend so that by loosening the nuts l desired adjustment may be readily made and said nuts then tightened up to secure the frame members at the desired point of adjustment.

In the case of large screens additional bracing may be desirable and this is shown in Figures 1, 6 and 7.

This additional bracing also serves to draw the screening 8 taut. As illustrated the additional bracing comprises an outside channel 20, preferably formed of sheet metal with its flanges folded inwardly and formed two ply, as shown in Figures 6 and '7. These flanges extend inwardly and the channel extends transversely of the frame and is preferably arranged midway between its upper and lower ends. A transverse metal bar 2| is fitted against the inner side of the screening and is secured in place, partly by the set screws 22 which are fitted through openings in the channel 20 and screwed into said bar 2|, as shown in Figure '7, so as to draw the slack material of the screening into said channel and to clamp it between said channel and bar, as shown in Figure '7.

The ends of the channel 210 and bar 2| are secured to side brackets which are secured to the side members 1, on the outer side thereof. These brackets are indicated generally by the numerals 22, 22. They are of T-shape construction. The heads of these brackets 22 fit against the outer sides of the side members I, I and partly surround the outer and inner margins of said side members. The legs of the brackets 22 extend transversely inwardly and partly surround the adjacent ends of the channel 20, as shown in Figures 1 and 6. The heads of said brackets 22 are secured to the side members I, by the clamp bolts 9 and nuts l2 which pass through them.

The ends of the channel 20 and clamp bar 2| are secured to the legs of the brackets 22 by means of the clamp nuts 23 which pass through said legs and through the channel 20, the screening andtheclamp bar 2| and whose inner ends are threaded to receive the clamp nuts 24, as shown in Figure 6. These clamp nuts 23 pass through longitudinal slots 25 in the ends of the channel 20 and bar 2| so as to permit the frame to be adjusted in width in an obvious manner.

The drawings and description are illustrative merely while the broad principle of the invention will be defined by the appended claims.

What we claim is:

1. In a screen, afra'me member formed of sheet material bent into approximately rectangular form in cross section, one of the free margins of said sheet being formed with a longitudinal V- groove opposite the other margin, means for drawing the sides of the frame member towards each other to seat said other margin into said groove and a screen sheet having a margin thereof clamped in said groove.

2. In a screen, a frame member formed of sheet material bent into approximately rectangular form in cross-section, one of the free margins of said sheet being formed with a longitudinal V- groove opposite the other margin, clamp bolts extending transversely through the frame member for drawing the sides of the frame member towards each other to seat said other margin into said groove and a screen sheet having a margin thereof clamped in said groove.

3. In a screen, a frame member formed of sheet material and bent into polygonal form in a cross section, one of the free margins of said sheet being formed with a longitudinal, approximately, V- groove opposite the other margin, means for drawing opposite sides of the frame member towards each other to seat said other margin into said groove and a screen sheet having a margin thereof clamped in said groove.
